Foster City customers on our AC service

★★★★★

Our AC quit during the hottest week of the year and they had a technician at our Foster City home the same afternoon. Fixed a capacitor, charged exactly what was quoted. Cold air within an hour.

Maria G., Foster City
★★★★★

Called three companies for a no-cool emergency in Foster City. These were the only ones who gave a real arrival time and actually kept it.

Angela D., Foster City
★★★★★

Our restaurant rooftop unit died on a Friday lunch. They came out that afternoon and had us cooling again before the dinner rush. Lifesavers for a business in Foster City.

Air Conditioning Service in Foster City: frequently asked questions

How often should my air conditioner be serviced?

Once a year, ideally in spring before the first heat wave hits Foster City. Systems that run most of the year benefit from a second visit in late summer.

Is AC service the same as AC repair?

Service is the preventive tune-up and cleaning; repair fixes a specific failure. Our service visit includes a full inspection, so if a part is failing we can repair it on the same trip.

Will service lower my cooling bill?

Usually yes. Dirty coils and low refrigerant can raise energy use by 20 to 30 percent. Cleaning and correcting the charge restores the efficiency your system had when new.
